Hi all,
I've got a solar geyser system installed using pumped system from collector to geyser.
My issue is that I'm losing >20 degrees geyser temperature overnight without using any hot water.
My current theory is that the pump is circulating hot water to the panel,so the hot water does not stay in the geyser and gets cooled down when circulating in the panel.
When I do heat the water up at night I notice that the collector temperature goes up as well to match the geyser temperature and then when switched off I lose more than 20 degrees temp in both geyser and collector overnight without using any hot water.
Is this a faulty installation? Should the geyser be pumping hot water to the collector like this?
